The benefits which in this life do accompany or flow from justification1 , are assurance of God's love, peace of conscience, joy in the Holy Spirit2 , increase of grace, perseverance in it to the end.3
1 Therefore being justified by faith, we have peace with God through our Lord Jesus Christ:
2 By whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God.
5 And hope maketh not ashamed; because the love of God is shed abroad in our hearts by the Holy Ghost which is given unto us.
